Product Description

 

Geomembranes

Geomembranes, which are often referred to as geomembrane liners,  are impermeable membranes used in conjunction with rocks or earth to block fluid migration in man-made structures. These membranes are usually made of synthetic polymers in sheets ranging from 0.25 to 3.5 mm thick. Geomembranes are made of various materials such as EPDM (Ethylene Propylene Diene Monomer), Linear Low-Density Polyethylene (LLDPE), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), and Polypropylene (PP).  Due to their ability to block fluids, they can help to prevent the dispersal of contaminants and may be used with soil liners or permeable geotextiles to create a composite lining system that provides added security.
Geomembranes are especially important for waste containment. Our products are manufactured from highly durable materials, often with an expected lifetime of hundreds of years. They are resistant to chemicals and wear so that the passage of time and corrosion does not affect the integrity of the geomembrane liner. Each type of geomembrane material has specific characteristics which affect installation procedures, lifespan, and performance.
 

Product Description

High Density Polyethylene (HDPE) popularity is primarily due to its low initial material cost and excellent UV & chemical resistance. This allows thicker sections of HDPE to be used in exposed applications where the cost of other materials may be prohibitive. 
HDPE is a versatile material that is used widely across many applications. One of the primary uses of HDPE is as a liner at the base of landfills, where its chemical resistance is put to use. HDPE applications also include pond linings and water containment projects.

Application

Properties of Geomembrane

Physical properties of Geomembrane

The following are the primary physical features of geomembranes in their unprocessed state:

• Measurement of the thickness (smooth sheet, textured, asperity height)
• Density
• Indicator of melted flow
• Per unit of area, mass (weight)

Mechanical properties of Geomembrane

To measure the strength of polymeric sheet materials, a variety of mechanical tests have been established. Many have been adopted for use in geomembrane evaluation. They are index versus performance tests, and they reflect both quality control and design.

• Elongation and tensile strength (index, wide width, axisymmetric, and seams)
• Tear resistance
• Impact resistance
• Puncture resistance
• Interface shear strength
• Anchorage strength

Conclusion

Determining the best type of geomembrane for your project can be challenging. Several factors such as cost, availability and applicability come into play. 

Of all the geomembrane types, HDPE is the most recommended because of its operational advantages. It complies with the environmental sustainability requirements, is cheaper than other geomembrane types and has a variety of applications. With its excellent mechanical qualities and long durability, HDPE geomembrane is a cost-effective solution for seepage control and leakage prevention in reservoirs and dams.

FAQ
1.The product is designed to fit your needs?
It is an undeniable fact that the product must be adapted to the specific needs of the client. There are local laws, including requirements for labelling or transportation, certifications,regulations, rules or laws.
Each work or application has a specificity that makes it unique. However, on the basis of this conviction, we cannot forget the absolute truism that a Safe Containment need for a usual type of pollutant should not be very different from one country to another or from one client to another. The Safe Containment objective is achieved based on certain limits which are common around the world.
2.Textured or Smooth Geomembrane?
A textured product is either needed or is not. This apparent truism needs to be remembered in many cases in which a product is specified for a project which clearly does not qualify to be designated as textured yet is designated as such, creating a huge confusion about the uncertainty of the client's needs.
If the client does not clarify they require, it is hardly feasible to offer the right solution in conditions comparable to any concurrent company.
3.Is a Geomembrane with a wider roll better?
There is a technical limit for manufacturing geomembranes. In high density polyethylene (HDPE), this is 7.5 to 8m. Beyond this limit, either the raw material is not an HDPE and is instead a softer material which enables the extrusion-header system of the machine to complete the geomembrane transformation cycle, or the uniform thickness or thermal treatment parameters of the raw material have been seriously compromised. Within these limits and exceeding a minimum width, under which it would be unreasonable to present a product for the Safe Containment application, the roll width is the choice of the manufacturer, usually subject to the presentation format and transport cost optimisation.
There is hardly any difference between the cost of machines for given widths.
Within these limits, it is true that a wider roll relieves installation costs in large projects by a small percentage; however it is always at the expense of a higher cost of handling bulk unit weight of the roll or overruns in the finishing of curves or corners.
4.Differences between LLDPE  and HDPE?
Linear low density polyethylene (LLDPE) and high density polyethylene (HDPE) are raw materials which are similar in terms of composition, but very different in their behaviour, as has already been discussed in previous sections.
HDPE has become a global standard for Safe Containment applications precisely for its unique properties and marketing an LLDPE as an HDPE in these applications is tantamount to offering a substitute product without any benefit to the client. Differentiating them is very simple. Requiring the MFI parameter would be sufficient. Below 1.2 for 190/5kg is an HDPE, and above is not. It's as simple as that.
